Osney Capital

The firm invests exclusively in early-stage cyber security companies headquartered in the United Kingdom. It targets pre-seed and seed rounds where the round size is below £5 million, providing first-cheque capital to founders. Osney Capital does not invest outside the UK or in sectors beyond cyber security, structuring its entire investment strategy around this single-country, single-sector focus.

The three named partners — Adam Cragg, Paul Wilkes, and Joshua Walter — run the firm. Cragg brings ecosystem-building and venture capital experience; Wilkes supplies legal and regulatory expertise from private practice; and Walter contributes senior operational leadership in the cyber security sector. Their profiles are listed on the firm's website, and no separate investment committee or external advisors are publicly identified.

The firm's public materials describe only direct early-stage investments into operating companies. There is no indication that Osney Capital allocates capital to external venture funds as a limited partner. Its portfolio page displays solely direct company investments across multiple cyber security categories.

The firm's mandate explicitly excludes any sector other than cyber security. Generalist technology, fintech, healthtech, climate, and deeptech are outside its scope. Within cyber, its public communications show no investments in non-UK companies, reinforcing the geographic and sector boundaries.

While Osney Capital has not publicly detailed its sourcing pipeline, the team's composition provides structural signals. Adam Cragg's background at MIT, NYU, and university commercialisation offices supplies an academic and startup-ecosystem sourcing channel. Joshua Walter's cyber security executive network and Paul Wilkes's legal network in the UK corporate and financial services community extend reach into founder and adviser circles. The firm's Cheltenham location further embeds it in the UK's cyber and intelligence cluster.

No philanthropic foundation, donor-advised fund, or separate investment vehicle is publicly disclosed. The firm operates a venture capital internship program targeted at individuals from non-venture backgrounds and is a signatory to the UK Investing in Women Code, but these are programmatic commitments rather than separate legal entities.

Osney Capital has not publicly stated a policy on co-investments. Its portfolio does not list co-investors in individual transactions on the website. The firm presents its investments as direct positions and has not publicised syndicate structures, co-investment rights, or partnerships with other venture capital firms.
